Beit 'ln'ovvn that I5 lSAMUEL C. BOUGHER, a 'citizen' of the United States,y and a vresident ol' Philadelphia; county 'ot yPhiladelphia', State o'l'- Pennsylvania., havelinvented certain ,new and useful Improvements"infRol tary Brushes,A ofV whichv the 'fqllowng is. .a Specification,L l,

Some 'of the; objects of the present 'invenl ltio'nfare to provide an improvedrotary wire brush;V td provide 'ai 'brush' ,particularly adapted vforjcleaiiing, scouring; or polishing back of the brush; and Fig. 5 represents av side elevation of the brush elements mounted ready for assembling with the base or suport. p Referring tothe drawings, one 'form of the present invention comprises a base 10 of fibre or any other'suitable material 'capable of withstanding working pressure at high speeds and having an axial opening` 111. to receive the reduced end 12 of a spindle 13 which is arrangedto be driven at a relatively high speedby suitable power means (not shown).

any well known means may be employed for the purpose.

The base 10 is arranged to carry on its l outer face 14 brush elements 15 consisting` in the present instance, of two annular` concentrically arranged brush units, 16 and 17` each ol' which is formed of a plurality of substantially V-shaped steel strands 18 assembled upon and held by a body in the vform of two twisted wires 19 and 2O.y Initially the two wires 19 and 20 are lineally arranged and twisted together in such a manner as to interweave the wire strands 18 so that all the strands extend in substantial alinement throitghout the length of the inertwisted wires, to form a continuous brush,r

A nut 14 serves to rigidly secure the base 10 to the Vspindle 13, though Maaate the respective strandsot which diverge from acommon iuris. "'The'linearlength'orlengthp -of-the brushes y sof ormed'is "predeterminecl f j y1n accordancewithqthe"size" of the' brush'- de- `60V l .i

v For the purpose of `shaping"the` brilishfo'f the present. inventionuand rigidly secnring, v it to the bas`e"1`0,""'a'` plurality"of-ifci'rcular-Y groove-S 21 and 22 are Cutinthe facev ia 'of thelbase' 10, having refspectiveflyl adep'tlh and width "suilici'ent."toy 'receive "the briish [retainare two 'such grooves fa Tangedffco-ncentric with resp`efct tor ythe.v axis fofj'rotationfof the brshQ' though this`arran'gement'` canloe` varied without depart-ing from the 1 inven tion.

These staples 23'are prefer! ably uniformly spaced angularly aboutthef4 base 10 and are readily placedv by lthe pro;

. vision of through holes 24,25 and 26 inthe base which are arranged in radially dis-` posed sets having two holes 24a-nd 26 lof a.

size to receive one leg of .a staple 23, and one y hole 25 to receive' two staple legs. yThuslin assembling, a staple 23 of `the outer brush' unit 1G has its legs passing yrespectively through the openings 25and 26 kof the base n 10, and astaple23`of theinner brush unit 17 has its legs passing respectively through staples thenv the openiniifs 24vand 25. both being clinched on the base 10..

i It will be notedv that the strands of the respective `units diverge respectivelywith a suiicient flare to projectcircumferentially beyond the periphery. of thebase 10 so that t the brush edge canl be used to clean corners or other angular locations `which are not vor-l dinarily accessible to the face of the bruslif4 From the foregoing it will be apparent that a complete unitary brush structure has been devised,V particularly adapted for ro-` tary high speed cleaning purposes whereinv flexible, stiff wire strands'are employed for im I brushing, scouring, polishing and scrubbing purposes, and are so constructed as to be firmly heldby the base to which the lpower y i agent, When arranged in a holder oftheltype here shown, and capablev of standing vup spindle is attached. Furthermore y=While brush strands of 'Wire areihere specifically described, it is to be understood 4that any other material mayA be employed Within the 'spiritl of the "i'nyenton' which is adapted it'o act as aneicient polishing or cleaning -rthen-'invention or 4the scope of the appended Claims. y n l,
